THE Upanishads, Buddha, and Śankara: these are the three great lights of Indian wisdom. The Upanishads far away in the golden age; in the bright dawn that has faded so many ages ago. Buddha, the Awakened One, who, catching in his clear spirit the glow of that early dawn, sought to reflect it in the hearts of all men, of whatever race, of whatever nation; sought to break down the barriers of caste and priestly privilege; to leave each man alone with the Universe, with no mediator between. But scattering abroad the rays of wisdom, Buddha found that the genius of each man, of each race, could only reflect one little beam; and that in thus making the light the property of all men, the purity and completeness of the light might be impaired. Then followed Śankaracharya--Śankara the Teacher--who set himself to the preservation of the light; to burnishing the casket that held the lamp of wisdom. Busying himself chiefly with India, he saw that the light must be preserved, as far as its completeness and perfection were concerned, within the Brahman order, where the advantages of heredity, of ages of high ideals and rigid discipline could best secure the purity of the light; could best supply a body of men, fitted by character and training to master the high knowledge, to sustain the moral effort that made the glory of India's Golden Age.BY CHARLES JOHNSTON
